It is known that the immune system reacts to foreign objects, which include viruses, bacteria, Rickettsia, etc. However, cancer cells are the immune system are not perceived as "foreign", resulting in cancer is often detected at later stages.
But if the immune system from the very beginning to react to abnormal cells, the development of the disease could be prevented.
Armed with this idea, the American experts led by David Kearney offered "label" cancer cells by viruses.
Such a method was proposed twenty years ago, however, experiments to date have not yet been conducted. The principle of the method is the responsibility of attenuated viruses in cells of atypical structure. Intracellular virus multiplication gradually leads to the fact that cancer cells are destroyed, and the virus appears outside. The separated proteins are thus detected viral immune system, and although the virus-infected cells are destroyed, together with them and killed cancer cells. The experiment was conducted with the participation of thirty volunteers with inoperable cancer of the liver, which is the traditional treatment methods can not help you. Especially that nineteen men appeared metastases. Such patients have initiated a modified vaccinia virus JX-594. Symptoms of the disease in humans resemble the flu, in addition, no adverse effects were observed. The results showed that the life expectancy of patients injected with the virus, is directly dependent on its input concentration. In some cases, patients who are projected to remain no more than six months to live, have lived for about two years. At this stage, the possibility of working professionals implementation of this technique in the treatment of cancer to another type of cancer cells. In particular, experiments are being conducted with atypical cells of the skin.
